A place to ask Canadians questions and get answers. The most obvious questions would be about Canada, but you can ask about pretty much anything; news, current events, society, etc

I don't intend this as an AMA format, but can entertain some. Rules:

  1. Be civil and act in good faith.
  2. No trolling.

Montrealers, do (most) planes at Trudeau airport land and take off towards the South-West? That would put it over the water, so the noise wouldn't be as bad. (lemmy.ca)

Planes take off and land into the wind so they don't crash. Runways are built in the directions wind blows, and wind direction tends to be pretty consistant, so an airport's runways often all face the same direction.

Some locations have very variable wind conditions so an airport may have runways in many different directions. For example, Wittman where they have Oshkosh has 4 runways in all different directions. http://img.airnav.com/aptdiag/w240/02539.gif?v=OY0UYO

Larger airports typically like to have more traffic throughput by having many parallel runways, like Atlanta which has all 5 runways facing east/west. This means planes may have to take off/land in crosswind conditions, which is not ideal but can be done. https://img.airnav.com/aptdiag/w240/02655.gif?v=Q88169

I have landed at ATL in a storm. I can confirm the first two points and the fact I can do so today confirms the last -- but it was a bit of a code-brown!
